The following describes the structure of the power collector principle:
The basic structure and composition
The collection mainly consists of solar batteries, the current-voltage conversion circuit, digital display devices, microprocessor control systems, power storage system composed of five parts.

Consisting of: ① solar array ②I / V conversion circuit (Hall sensor, power amplifiers, voltage meter) ③V / V conversion circuit (attenuator) ④ digital display device regulator device ⑤ ⑥ ⑦ battery micro-controller
2.2 Working Process
????Their work is the solar cell receiving sunlight internally generated current, the battery charge, the microcontroller through the regulator means provided by the battery drive voltage of the power generated by the solar cell signal acquisition, as the device can only receive voltage signals, and can not exceed 5V, so before the signal is received by the I / V, V / V conversion circuits of the signal is adjusted to a suitable voltage, the internal operation processing results sent to a digital display device displays the total amount of battery power.

3.6 daily management and automatic alarm system
Although solar photovoltaic electricity mains complementary forms of solar street lights in the city a good way to local conditions and application of solar photovoltaic lighting, to overcome the lack of reliability of a conventional solar lights, the system is very high, but the reliability of electricity sometimes overshadowed Solar street light failure; that is, solar lights broken, managers do not know. So we should daily management of solar photovoltaic electricity mains complementary forms of solar lights and higher requirements; the first to be equipped with certain hardware.
In hardware, the easiest to install lights in the apparent position of the solar photovoltaic system works display device. Usually with a green color or red color of LED solar street light or solar panels to the top edge of the composition of the display, indicating that solar street light is provided by solar photovoltaic energy system, otherwise described system has been switched to the mains, and this may be due to the sun insufficient amount of radiation, it could be a solar photovoltaic system failure.
Since solar photovoltaic and solar electricity complement each other in the form of street lighting system in the presence of power lines, power line carrier so its daily management and automatic alarm is the best approach. Moreover, present a variety of power line carrier communication module has been more mature, the price is relatively low, and single-chip computer which can be easily combined into solar photovoltaic and solar electricity complement each other in the form of street lighting system in the daily management and automatic alarm system.

3.1 related technologies lacking
Although the use of solar lighting system devices has become increasingly widespread, but on the power of solar street light efficiency and service life still exist some problems. According to the survey, for a relatively narrow road, rural roads to less demanding in terms of lighting, small power solar lights can meet; but for the higher requirements of urban street lighting, the solar street light, but there is still to learn: Light Coverage low, uneven brightness. Zhuhai pilot before the promotion part of the solar street light use, there is relevant personnel said that the current technical specifications of solar street view, it does not quite meet the illumination requirements lose the main road, so most of the city still does not use solar lights instead of the original Some of the main road street lights.
Also, the life of the solar panels also restricts promote the use of solar lights. From the previous survey, solar panels conversion rate, high cost. If you want to make the lights a bit longer, it should improve the allocation, rational matching portion of each component, rather than simply increase the battery capacity.
In addition, solar street if you want to be more widely used, in addition to considering solar panels installed photovoltaic conversion efficiency, but also consider local time solar radiation, atmospheric dust.

3.2 Environmental Pollution
The greatest advantage of solar lights is that it is the most clean solar energy, every street has a small generator. But the solar lights are mainly used in the battery lead-acid battery-based, it is mainly composed of lead, sulfuric acid and some other metal and plastic composition, waste battery acid contains a lot of lead, random emissions will not only seriously polluted soil and water, will air, causing damage to the ecological balance, but also lead to human metabolism and neurological diseases. At present, domestic waste recycling is still in relatively disordered state, so a lot of used lead-acid battery is being scrapped after polluters our living environment. In the development of solar lighting products are considered to be multifaceted, reducing product contamination of the environment. Related industries should accelerate technological innovation, as early as possible to achieve recycling polluting batteries that would make our living environment and solar street light industry severely affected.

Control the color, changing the distribution of light，resulting in dynamic mirage is possible, so it is particularly suitable for application
in solar lawn. Many of its inherent characteristics, the use if attention will be adverse consequences. But the LED current sales in the market LED luminous efficiency can only reach 15Lm / W, can only achieve three-color color energy efficient lamps 1/3, the luminous efficiency three-color color energy efficient lamps can reach 50 Lm / W ~ 60Lm / W
Price-wise, the current production cost per Lm: the three-color color energy efficient lamps (with electronic ballasts) 0.022 yuan, 2002 f5mm white LED price of 1.9 to 3.0 yuan, the current high production costs per Lm, the price difference poor.
From the point of view life, three-color color energy efficient lamps (with electronic ballasts) of life can reach 6000 hours, LED can reach more than 100,000 hours, on the surface, LED life is a three-color color energy efficient lamps (including electronic Ballast) a few times, but that is not true. Most current solar lawn lamp ultra bright white LED, its super bright white LED lumen maintenance at 20mA reach the initial intensity of 50% at a time (life) is less than 10,000 hours, Fudan University have demonstrated above-mentioned light source argument. This means that in many cases now is not the best solar LED lawn light, unless it is low-grade, the age of only 1 to 2 years of solar lawn, or less than 1w solar lawn.
For more than 1W solar lawn, preferably using a three-color color energy efficient lamps.
There are a number of solar lawn by 30 to 40 super bright white LED, input power 2W or more, in this case, if the if the three-color color energy efficient lamps, LED price is only 1/10 of the original luminous flux four times, and now has successfully developed low voltage DC 2 ~ 10W tri-color color energy efficient lamps, life can reach 6000 hours.
Based on the above analysis, we believe there is adjust the brightness, 1W power solar lawn little less frequent switching function, the general should use LED as a light source. However, the use of ultra-bright white LED lumen maintenance with particular attention to the issue, otherwise easily lead to accidents. For larger power solar lawn, currently using a three-color color energy efficient lamps is reasonable. It should be emphasized that the above conclusion is analyzed only when LED technology after improving the level of prices, the need to change the above conclusions. For solar garden lights, from reliability, cost performance, color temperature, and luminous efficiency aspects into account, we believe that the ideal light source should now be three-color color energy efficient lamps.

As the input battery energy solar photovoltaic system unstable, it is generally required to configure the battery system to work, solar lamps is no exception, you must configure the battery to work. Lead-acid batteries generally, Ni -Cd batteries, Ni-H batteries, their reliability and system capacity options prices directly affect the system.
Choice of battery capacity generally follow the following principles:
First, to meet the night lighting under the premise of the energy as much as possible during the day a solar cell module stored, but also capable of storing electrical energy to meet the continuous rainy days night lighting needs. Battery capacity is too small can not meet the needs of lighting at night, the battery capacity is too large, while the battery is always in a state of loss of electricity, affecting battery life, while wastage. Battery selection also depends on the solar cells, the load is determined, let's be introduced in the system design.

?Load solar lighting products to energy-saving advantages, of course load to energy saving, long life. We generally use LED lights and 12V DC energy saving lamps and low pressure sodium lamp. At present, most lawn use LED as a light source, LED long life, it can reach more than 100,000 hours, low voltage, very suitable for use in solar lawn.
Garden lights generally use 12V DC energy saving lamps, energy-saving lamp voltage DC to DC, no inverter, convenient and safe.
12V DC energy saving lights generally use low pressure sodium lamps and low-pressure sodium lights high efficiency (up to 200LM / W). However, due to the low-pressure sodium lamps are expensive, use less.

?The shell we collected a lot of information on foreign solar lights, aesthetics and energy between the two, most have chosen to save energy. Exterior lighting requirements not high relative utility line. There are many manufacturers look very pretty, with stainless steel housing. But the performance in the end what? This brings us food for thought! Solar lighting system design a good product, the key lies in the system design, what is the rational system design? Let us first look at a few important factors which affect it!
